Act as a product designer with 5+ years of experience in kitchen gadgets. Design an AI-powered hand grinder that automatically adjusts coarseness settings based on the type of [COFFEE_BEAN], [BREW_METHOD], and [USER_PREFERENCE]. The grinder should feature a sleek, ergonomic design with a built-in display showing real-time grind settings.
